Brief Biography

   Dong-Hoon Choi received the B.S. degree in electrical and electronic engineering form Yonsei University, Seoul Korea in 2007 and M.S. degrees in Electrical Engineering from Korea Advanced Institute of Science and Technology (KAIST), Daejeon, Korea in 2009, where he is currently working toward the Ph.D. degree in electrical engineering at KAIST. During his M.S. research, he worked on linearly variable inductor with RF MEMS switches to enlarge a continuous tuning range. In this research, he proposed the combination of continuous and discrete variable inductor to enlarge to the continuous tuning range of inductance, and developed the fabrication process to integrate RF MEMS switches and a high-Q solenoid inductor. His work was accepted to present at the International Conference on Solid-State Sensors, Actuators and Microsystems (Transducer ‘09). 
   During his Ph.D research from 2009 to present, he has been studying on a columnar nanoporous membrane. He proposed and demonstrated for the first time that a generally sputtered thin film can be exploited as a versatile nanosieve, and related works were published in Advanced Materials and IEEE International Conference on Nanotechnology (IEEE NANO ’10). Proudly, the work published in Advanced Materials was selected as a Cover Picture. Also, he invented and demonstrated a new type of liquid-based electrostatic energy harvester for human physical movements, and related works were published in Smart Materials and Structures, and the International Workshop on Micro and Nanotechnology for Power Generation and Energy Conversion Application (Power MEMS ‘10). 
  During Ph.D courses, he has cooperated with various types of colleagues’ researches (ex. trans-scalable nanofabrication, super-hydrophobic surface, MEMS variable capacitors, MEMS packaging, and MEMS switches), and worked as teaching assistant in several lectures.
